The rapper accused of roughing up a porn star outside a Meatpacking District nightclub isn’t likely to face felony charges because — contrary to what the victim first claimed — no weapon was used and the victim had no visible injuries, sources said.

“First she told cops she was hit with a bottle but then she backed off from that and said that it never happened,” a law enforcement source explained.

Mellanie Monroe was inside rapper Maino’s truck outside of the Griffin around 3 a.m. Tuesday when she claims he punched her in the stomach and ribs and kicked her in the leg, according to police. A rep for the rapper denies he was violent.

Officers at the scene and security helped her out of the vehicle and the two parties left in the same direction, with the rapper in the truck and Monroe on foot.

“She walked off in the same direction with two fans,” the source added.

At the corner of Washington and Gansevoort streets, “she saw his truck parked and threw a hairbrush at it,” the source said. “That’s what she told police.”

The pair began arguing again, but this time Maino, whose real name is Jermaine Coleman, stayed inside the vehicle, while his security stood by with a Champagne bottle that he appeared to be trying to open, the porn star told police.

“At no time was she hit with the bottle, although she perceived it as a threat,” the source continued.

Monroe then began arguing with the security guard and grabbed the Champagne bottle, and the pair fell to the ground in a struggle, causing the voluptuous blonde to bash her head on the ground, she reported.

Video confirmed the first part of her story, but her recollection, which changed, is the only evidence of the second altercation, sources said.

There was no weapon and there were no visible injuries, so the alleged assault is likely to be classified as a misdemeanor, sources explained.

Maino’s reps said he was at the hotspot celebrating the recording and mastering of “King Of Brooklyn Part 2” when “a loud, belligerent young lady, whom he did not know, was escorted from Maino’s presence by the kind officers working outside of the venue.”

“Maino thanked the officers and simply drove of and at no point did he and the woman ever make any physical contact at all,” the rep said. “My client and friend of ten years, Maino is respectful of all upstanding women in our community.”

He added that the victim has been spreading “a lie, looking to gain attention” and said video evidence would exonerate the rapper.
